分布式光纤法在旋挖成孔灌注桩桩身内力测试中的应用

The application of distributed fiber optical technology in the internal force testing of excavation drilled-pouring pile

采用分布式光纤法对旋挖成孔灌注桩进行内力测试,通过测得基桩的应变分布,计算侧摩阻力和端阻力,与勘察提供的桩基设计参数进行对比,为以后优化类似设计提供了一定的工程应用意义。

By the method of distributed fiber optical technology to internal force test of excavation drilled-pouring pile,we get the stress distribution of the pile and calculate pile lateral friction and tip resistance of pile which compared with design parameters of pile foundation by survey report.It provides certain engineering application meaning for the optimization of similar design in the future.
